An enclosed kitchen is easier to keep clean than an open floor plan kitchen, for example, because items are contained within the physical limitations of the space. Or, at the very least, the closed kitchen can be exited with a door shut behind, limiting the mess’ effect on the rest of the household and space, particularly the main, high-traffic rooms.
